Now that my title has your attention, I’ll be a little more specific. Whirlpool suggests that it’s Speedcook microwave can be used as a proofing box for maintaining an appropriate and steady temperature while proofing breads. Home bakers who are trying to create their own artisan breads often find the loaves rising either too quickly or too slowly depending on the ambient temperature of the room. Whirlpool suggests these steps to help bakers keep a proper temperature:

Using the convection setting:
Place dough in a lightly greased ovenproof bowl, and cover
loosely with shortening-coated wax paper.
1. Place a shallow, ovenproof container, such as a pie plate,
filled with 2 cups (500 mL) boiling water on the turntable.
2. Place the convection rack on the turntable, and then place
the bowl of dough on the convection rack and close the door.
3. Touch “Time/Temp/Power” on the Main Menu, then select
“Bake.”
4. Follow instructions on the display to program the proofing
time (about 45 minutes).
5. Touch “Temp 350°,” and then set a temperature of 100°F
(38°C) using the “-” control or number pads.
6. Touch “Start Preheat,” and then touch “Skip Preheat.”
7. Touch “Start” on the touch screen, or START control.
The display will count down the proofing (baking) time.
Check dough after 20 to 25 minutes. Proofing time may vary depending on
the type and quantity of dough. Proofing time may be
changed during the countdown by touching “Adjust
Settings,” and then following the instructions on the display.
When the cycle ends, the end-of-cycle tones will sound,
followed by reminder tones.
When proofing is done, remove bowl of bread dough and continue with your recipe as desired.

If you own the Speedcook and would like to let us know how this works, we’d love to hear from you.
